strange symptoms

i had been taking 10mg endocets for about a week and a half after a bad ankle sprain.i was told that a muscle relaxer would work at 4mg.i took the muscle relaxer and within an hour and a half of falling asleep, i awoke anxious, unable to catch my breathe, congested beyond any other congestion i've experienced and could not fall back to sleep (possible insomnia?)

it is almost 48 hours later and after laying in bed all day yesterday, i still feel sluggish and warn down, drowsy, midly congested and am overly aware of my heartbeat. i am also still a bit anxious.
